Specification of Letters Patent.

Patented sept. ie, 1ers.

Application filed September 11, 1917. Serial No. 190,813.

To all 'whom t may concern.'

Be it known that HERMAN MAnGoLis, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Clutch Mechanism; and he does hereby ldeclare the following to be full, clear, and exact description ofy the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in clutch mechanism for machines of various kinds and controlled by suitable treadle mechanism. A

My invention consists further in a simple and eiiicient device of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically deined in the appended claim.

My invention is illustrated in the accompanyingv drawings, in which:

Figure 1 is a side elevation, showing the application of my invention to a sole cutting machine. Fig. 2 is a sectional view on line 4 4 of Fig. l, showing in plan view the clutch mechanism, Fig. 3 is a sectional view on line 5 5 of Fig. 1. Fig. 4 is a sec'- tional view on line 6 6 of Fig. 1, looking in the direction of the arrow. Fig. 5 is a de tailed perspective view, of a part of the clutch mechanism. Fig. 6 is a sectional view on line 8 8 of Fig. 2. Fig. 7 is a vertical sectional view on line 9 9 of Fig. 6, and Fig. 8 is a sectional view on line 10 10 of Fig. 6.

Reference now being had to the details of the drawings by letters:

A designates the frame of a sole cutting machine in which a driving shaft B is journaled in suitable bearings. Mounted to have a vertical adjustment upon said frame is a bed C upon which the article to be cut rests, and E designates a die cutter, shown in dotted lines, which may be of any shape or size adapted to be placed upon the work to be cut. Said bed has bosses C projecting from the lower portion thereof which are centrally threaded to receive the screws C2 mounted in the bearings C* upon the frame frame is a beam G which imparts a blow tov the die for the'purpose of cutting the sole from the material beneath. Said beam has shouldered portions G adapted to guide the beam in its vertical movements, and plates H are fastened to the ends of the beam and also serve as guides.' Studs J project one from each end of said beam and upon which are mounted a block M, through which the upper ends of the rods O pass. Similar blocks Nv having circular outlined openings for the reception of the eccentric disks Q, fixed to the shaft B are mounted on the lower ends of the rods O. By this mechanism, it will be noted that as the shaft B is driving pulley W is loosely journaled upon the shaft B and has a boss W projecting from its inner face and from which project diametrically opposite lugs W2, having each an inclined face W3 (Fig. 5 of the drawings) and which are adapted to contact with the key R when the latter is thrown out into the paths of said lugs W2. The purpose of said spring is to normally hold the key in such a position that its outer end will project beyond the outer face of the collar and in the paths of the lugs W2 which projectv from the face of the clutch disk T', which latter is j ournaled loosely upon the shaft B and is driven continuously by any power, not shown.

Pivotally mounted upon a shaft S projecting horizontally from the frame is a lever X, shown in Figs. 1, 2 and 4 of the drawings, having a slot X formed in one path of the finger R3.

end thereof. The end of one wall of said slot is provided with an aperture Y adapted to receive the locking pin Z which is pivoted at one end to the angled member X4, which is pivotally mounted upon the pin X5 upon the lever. Said member X4 has a flattened"- end finger X6 which is adapted to be posi# tioned across the inner end of the slot in the end of the lever and forming an abutment against which the finger of the locking key is adapted to contact, for the purpose of positively throwing the pin Z intoalocking relation with reference to said linger. pin Z and bears between the edge 'of lever X and the pinv Z, as Shown in Fig.l 6 of the drawings, on said locking pin Z and servesto hold the locking pin out of locking position.

A treadle, designated by letter L2 is pivotally mounted upon the shaft Ii" upon the frame and is held at its upper limit through Vthe medium of the springs L4L which are fastened tothe treadle at their-lower ends and their upperv ends to the cross piece L5 of the frame, and Lx designates a link pivotedy at one end to the treadle and its other end to' Vsaid lever'.

In operation, itwill be understood that the shaft and collar carrying the same are normally at rest .with the key held back within the collar and wheny it is desired to permit a single revolution to be imparted to the shaft B for the purpose of cutting the sole,v the operator by depressing the treadle toits lowest limit and immediately releasing the latter will cause the lever X to tilt upon its pivot and its forwardend will be thrown out of engagement with the {inge-r upon said key, permitting the latter to be thrownfout into the path of one of the lugs Vuponthe continuously rotating driving disk. VAs the lever X is tilted by the depression of the treadle to its lowest limit, the slotted end of the lever X will release the key R, and when the end XG of the lever X* rises above the upper end of the finger 'R3 of said key,` the spring S2, inter osed between theslotted end of the lever i 4, en-A gaged by the Ilug X of the member Z, willV cause the lever X4 to tilt upon its 'pivot and the member Z will be withdrawn out of the Immediately after the treadle is depressed and released, it will Copesof this patent may be obtained for A spring S2 is mounted' upon thel return to its normal position, as will also the lever X, through the medium of the springl L4. After theV collar has made a complete revolution, the nger of the key coming in contact with the inclined portion of the lever, will cause the key to be thrown out of engagement with the clutch lug NVZ, and as the linger comes in contact with the end X6 of the lever X4, said end X6 will Serve as a stop, the key of the member Zv be- Each time the treadle is depressed and immediately released, a single rotary movement will be imparted to the collar .and parts actuated thereby.

By the foregoing mechanism, it will be une derstood that by a single rotary movement being permitted to the collar and the recip-V rocating beamactuated thereby for the purpose of imparting a blow to the cutting die, the parts may be stopped automatically after the beam has struck the die and returned to its starting position.

What I claim to be new is:

A clutch mechanism, comprising a frame, a driven shaft, and a continuously rotatable pulley looselyjourn-aled thereon, clutch lugs projecting fromy said pulley, a collar keyed to the driven shatt, a spring pressed key mounted upon said collar, and having a nger projecting therefrom, a tilting spring the treadleV actuated level', a spring pressed pin pivotally connected to said angle lever and movable thro-ugh aj slot in the treadle actuated lever, one end of the angle lever adapted to be positioned in the path of said finger, against which it contacts, as the collar makes a single revolution, and a spring pressed locking pin carried by the angle lever.
